Abstract (en)
[origin: EP0066661A1] 1. Hot-air drying apparatus, with a simultaneous lifting action, for continuous strips of flexible material, in particular strips of paper leaving offset printing units, of the type comprising a casing (2) inside which there are arranged, between an entry opening and an exit opening (3a, 3b) for the strip, two rows of blowing members (9c, 9d), one of which is arranged above and the other below the plane of movement of the strip, these blowing members having air-ejection slits (10) which are oriented transversely in relation to the direction (D) of movement of the strip, these slits facing the strip (B) to be dried, the said blowing members (9c, 9d) being connected to at least one recycling fan (23a, 23b) and to a heat source (24), the casing (2) being connected, moreover, to an extraction fan (38), apparatus characterized in that, in the direction (D) of movement of the strip, the casing (2) consists of at least two separate sections (5a, 5b) fixed to each other, each of these sections comprising a blowing assembly (23a-9c-9d, 23b-9c-9d), the latter comprising two rows of blowing members (9c, 9d) and a recycling fan (23a, 23b), the intake side of which communicates with the internal volume of the section of the casing (2) and the delivery side of which is connected to the said rows of blowing members (9c, 9d) by ducts (12c, 12d) provided with heat supply passages (27) connected to the heat source (24), and in that each of the two entry and exit openings (3a, 3b) for the strip is equipped with two blowing members (4a, 4b), one of which is located above and the other below this opening (3a, 3b) and which are oriented transversely in relation to the direction (D) of movement of the strip and each have, over the entire width of this strip, at least one air-ejection slit (21c, 21d) facing the strip (B) to be dried, these blowing members (4a, 4b) being connected (36) to the delivery side (35) of a fan (34) which sucks in air from outside the casing (2) of the apparatus, this air being preheated with the aid of preheating means (24-26-36, 16).
